Answer:
Step-by-step explanation:
1. Area of base
The radius given is that of the circumcircle.
The general formula for the edge length a of a regular polygon is
a = 2Rsin(π/n)
So,
a = 2 × 5 × sin(π/5) = 10sin0.6283 = 10 × 0.5878 = 5.878 in
The general formula for the area of a regular polygon is
A = ¼na²cot(π/n)
So,
A = ¼ × 5 × 5.878²cot(π/5) = ¼ × 5 × 5.878² × 1.376 = 59.44 in²
2. Lateral area
The general formula for the lateral area L of regular prism is
L = nah
So,
L = 5 × 5.878 × 12 = 352.7 in²
3. Total area
Total surface area = lateral area + 2×base area
S = L + 2B = 352.7 + 2 × 59.44 = 471.6 in²
The formula for volume of a cylinder is V=π r^2 h.
So plug in,
320π=<span>π r^2 20
solve (sadmep (opposite of pemdas))
divide pi out
320=r^2 20
divide 20 out
16=r^2
square root of 16 is 4, so the radius is 4.
Since the 2r=d, the diameter is 8.
P.s. lol it thought I was copying an answer from online...

Your answer is B.
<h3><u>
What are expected outcomes?</u></h3>
Expected outcomes are forecasted results. Think of expected outcomes as your program’s hoped-for results for children, families, and the community. Frame your outcomes to answer this question: "What results do we want?" Expected outcomes relate directly to program goals and objectives.
Yw and pls mark me brainiest, and I sure hope this helps you
Because by dividing both equations you get an answer of 8 for both
